Have a look on the nearside of the 'A' frame as that is where they used to locate the plate with the caravan details. It should state the year of manufacture and the weight but it won't be listed as MIRO or MTPLM but more than likely the 'Unladen' and 'Gross Laden' weights.
When we started caravanning in the early seventies the caravans had the serial number stamped on the A frame.You may have to take the A frame cover off if it is not on the under side as some were.From memory the first two digits were the year, ie 89 would be 1989.
Yes, I would suggest that it would be as 1990 model. Also Have a look at the chassis number and then give Eldiss a call to see if they have any record of it but I wouldn't raise any hopes but every avenue is worth a try.
